HANG-AR Application filed July 1, 1930. Serial No. 465,227.

This invention relates to hangars and more particularly to hangars for reception of lighter-than-air crafts.

among the principal objects which the y Y present invention has in view are: To provide v A on to the wind; to provide a roof having an opening therein which can be positioned in the direction in which the wind may be blowing.; to provide means for lowering the craft into the hangar through the roof; to

i provide means within the hangar for receiving air-craft, and to move same to various positions within the hangar; to secure simplicity of construction and operation; and to obtain other advantages and results as may 25 be brought out in the following description.

In the drawings:

Figure 1 is a plan view of a hangar providedy with a rotatable roof and an opening.

l therein; Y Figure 2 is a sectional view as taken on the line Q-2 of Figure 17 and Figure 3 is an enlarged fragmentary detail sectional view showing means of rotating roof of hangar.

ln the description: lt is well known that the hazard of present day mooring and launching of aircrafts, particularly the dirigible type, is adverse winds. Y Considerable time is lost in waiting for winds to die down in order to successfully moor a dirigible to a mooring mast or bring it down to the ground preparatory to placing it in a hangar. Also, to accomplish bringing the dirigible to the ground requires vast man power. and then the dangers are not eliminated. foi` should a sudden gust of wind blow up, the efforts of the ground crew are made considerably7 more hazardous and may cause 60 possible damage to the dirigible. These same difficulties are encountered when moving a dirigible out from the hangar.

To overcome the above conditions, I have shown in my disclosure a hangar 10, preferably constructed of a cylindrical shape. Said hangar is provided at the top with a rotatable roof 11 of similar shape and fiat surface, and provided with an elongated and preferably oval opening 12 for lowering or releasing aircrafts therethrough, and particularly aircrafts of the dirigible type. Said roof is made rotatable with respect to the side walls and may be rotated by any suitable means so as to position it to receive a dirigible coming in a direction with a favorable wind. However, in use, it is not absolutely essential to first rotate the roof so that the opening shall be in alignment with the craft, as I have provided a stationary mooring mast 13 adjacent one end of the opening. said mast being provided at the upper end with a pivoted member 14 to which the nose of a craft 15 (indicated in dotted lines) is first moored. After the craft has been thus moored, the roof may then be brought around for the opening 12 t0 be in position underlying the craft and longitudinal thereof.

When the roof with the opening is in the position required, a second mast 16 preferably of a mobile type oppositely positioned on the roof at the tail end of the opening is brought up in place or moved backward depending on the length of the craft to be moored. The tail of the craft is then securely attached to this tail mast as clearly shown in Figures 1 and 2. When the craft has been securely moored to both masts, the attachment of the craft is transferred from the pivoted member 14a to a means within upright slides 17 secured to both masts. Said 90 means may be cables 18 (indicated in dotted lines in Figure 2), which are attached at their lower ends to a pair of motor-driven drums 19. Said drums are operated simultaneously when the craft is being lowered down and slides 17 so that the cra-ft is 1n an even position all the way down.

When the craft has been brought down to resting position on the floor of the hangar, the lowering means may be removed from both ends of the craft. Should it be desirable to move the craft out of the way, Ythe n ose and tail may then be made secure to aholding means within ahorizontal track21here shown as extending peripherally of the wall and carried by framework outward from the interior wall of the hangar 10'as shown in Figure 2'.V v

To further secure the craft in the hangar,V I have provided docking rails 22m the floor l The opening12 in the roof 11 is rotated while the craft is being lowered of the hangar.

so as to be in alignment with the said docking rails, and when the craft has been entirely lowered, it is then fastened to the rails, after which thecraftrmay be' secured tol the holding means 2O inthe walltrack21. t i

vIn order-'to launch a craft,.it isfirstreleased vfrom the docking rails, after which "the craft is brought around 'tot bein alignment. with the slides 17 andk then released fromthe wall Y i track andvmade secure tothe holding means 18 withinV the slides. The roofl is then rotatediwith the craft to be in alignment -with the prevailing wind and the craftiisgthen permitted tol riseunder its own buoyancy to. the top' of themasts 131 and'16`.' When the craft has reached the top of the slides, the holding means in the slide'of the mobile mast 18 is Vto right itself and clear the said mast, after which the holding means inmast 13 is. detached, and the cra-ft under' its ownr power sail'saway.

On' the top of the hangar 10and extending entirely around the periphery4 thereof, I have 'shown a pair of railway tracks23,'though other means may' be employed for supporting and guidinga plurality'o' wheel's24vmounted ont-he underside of the roof11.L Said wheels Yarepreferably'of the car typehaying inwardl facingiianges 25to fitl and extend below t e-surface of the tracks; Any suitable: means may be' used to rotate the roof., such as'iautomotive power andi so'l forth.

The mobile mast 16 as illustratedis pref-- erably mounted on a track 261 havingA a2 pluralityof wheels 27 riding cna pairofftracks 28 securely fastened to the roof 11. Said tracks extend in a direction longitudinally ofthe; opening 12 and at their forward' ends extend slightly beyond said opening; Adjacent the out-side periphery ofthe Vroo-f the tracks 28v are turned upward seas toprevent the track 26 carrying the mast 1:6 from becoming disengaged ltherefrom when moved backward, as wh'enfal ship substantially the length'ofthe'opening is to be lowered into i the hangar 10;

Iny inclement weather, a cover of any def sired size or weight may be employed to close the opening l2. Said cover maybe'permanently attached to the "roof" oriplaced there y during bad weather desiredf From the above disclosure itisto belnoted lthat largeV crews for handling a dirigible for mooring and launching is eliminated, and the hazards have been greatly minimized. While I have not shown any means for entering the hangar or to reach the top of the roof, doors may be conveniently placed in the hangar and ladders eitherk inside or outside the Vhangar may'beemployedto reach the roof.
